Abstract:
High-resolution X-ray spectroscopy has advanced our understanding of
the hot Universe by revealing physical properties like kinematics,
temperature, and abundances of the astrophysical plasmas. Despite
technical and scientific achievements, the lack of scientific products
at a level higher than count spectra is hampering complete scientific
exploitation of high-quality data. This paper introduces the Catalog
of Ionized Emission Lines Observed by the Reflection Grating
Spectrometer (CIELO-RGS) onboard the XMM-Newton space observatory.
The CIELO-RGS catalog aims to facilitate the exploitation of emission
features in the public RGS spectra archive. In particular, we aim to
analyze the relationship between X-ray spectral diagnostics parameters
and measurements at other wavelengths. This paper focuses on the
methodology of catalog generation, describing the automated
line-detection algorithm.
A moderate sample (∼2400 observations) of high-quality RGS spectra
available at XMM-Newton Science Archive is used as our starting point.
A list of potential emission lines is selected based on a multi-scale
peak-detection algorithm in a uniform and automated way without prior
assumption on the underlying astrophysical model. The candidate line
list is validated via spectral fitting with simple continuum and line
profile models. We also compare the catalog content with published
literature results on a small number of exemplary sources.
We generate a catalog of emission lines (1.2x104) detected in ∼1600
observations toward stars, X-ray binaries, supernovae remnants, active
galactic nuclei, and groups and clusters of galaxies. For each line,
we report the observed wavelength, broadening, energy and photon flux,
equivalent width, and so on.
Description:
CIELO-RGS is the first catalog of high-resolution emission lines
measured by the Reflection Grating Spectrometer (RGS) instrument on
board XMM-Newton, based on the database of spectra available in the
XMM-Newton Science Archive (XSA).
